Avantgarde Acoustic Duo SDThe Duo SD takes the Uno SD recipe (detailed elsewhere) and scales it up, both physically and also technologically. In comparison the Duo features a larger mid range horn which means it can work down to even lower frequencies and therefore reduce the crossover point to the bass system. The driver is larger too, up from 5" to 7" and an Alnico magnet is used, which are rightly prized for their improved texture, speed, reduced grain and more natural

Its great!
For relentless. itching! I just wet my arms and legs then rub the bar on them lightly. Then rub it over the wet skin for a goid suds. Wait a few minutes and return to rinse it off wth was cloth etc. It really cuts the itch. You have to repeat this every several hours. But if you are able to work with it, its a wonderful soap and not drying! For severe eczema, and histamine itching, this reduces it with zero side effects. Verynice!!
